Whole-rock elemental analysis for lower Pliocene marine sediments from IODP Site U1533, Amundsen Sea, Antarctica

Major and trace element geochemistry of lower Pliocene marine sediment core samples collected at International Ocean Discovery Program Site U1533 in the Amundsen Sea via ICP-MS. Bulk samples of mud or sandy mud were analyzed to assess sediment provenance using elemental ratios. The geochemical data were collected and analyzed by Olga Libman-Roshal and Sandra Passchier, assisted by Xiaona Li in the ICP-MS analytical work.针对采集自阿蒙森海国际大洋发现计划（International Ocean Discovery Program）U1533站位的上新世早期海洋沉积物岩芯样品，本数据集提供其常量与微量元素地球化学特征数据，相关分析采用电感耦合等离子体质谱法（ICP-MS）完成。本次分析以泥质或砂质泥全岩样品为对象，通过元素比值法评估沉积物物源。该地球化学数据由Olga Libman-Roshal与Sandra Passchier采集并分析，李晓娜（Xiaona Li）在ICP-MS分析工作中提供协助。
